• Warehouse Temperature: 24-28°C (stable, not overly cold).
• Defect Rate: Dropped from 15-20% to under 2%.
• Carton Moisture Content: Reduced by 30-40% compared to previous levels.
• Storage Duration: Significantly extended without mold concerns.

💰 ECONOMIC BENEFITS OF HUMIDITY CONTROL

"After installing the DeAir.RE-600H heat-pump dryer, our warehouse environment completely transformed. Humidity is stably controlled at 45-55% RH, cartons no longer mold or peel, and our goods are preserved much better. Most notably, the defect rate dropped from 15-20% to under 2%, saving us 500-700 million VND annually. The machine operates very quietly, saves electricity, and the DeAir support team has been incredibly dedicated."
